If your doctor said it was ok, then I would say it's fine- but there are some things you should think about. From what I understand, it can still be painful and cause irritation. Also, you need to be sure that unprotected sex with your partner will not cause another issue- such as pregnancy or STD (if they have one for instance). Personally, I'd probably wait until it was healed just to avoid any further irritations- especially if I had the condition for that long.
What is, “ zoom balanitiis?”
